Title: Improvements in or relating to thermionic valves and other electric discharge devices
IPC: H01J1/15
Filed: 1936-07-10
Abstract: 476,758. Thermionic valves. M-O VALVE CO., Ltd., and LE ROSSIGNOL, R. July 10, 1936, No. 19163. [Class 39 (i)] In large thermionic discharge tubes, the filamentary cathode structure is in the form of a hexagonal prism whose axis is parallel to the axis of the tube and of which the sides are formed by parallel short lengths of tungsten wire 4, perpendicular to the axis of the device, and supported in pairs by radiating molybdenum strips 3 lying in planes passing through the axis of the device. Each set of strips is carried by an axial water-cooled copper bus-bar 1 which are connected to the six terminals of a hexa-phase supply so that alternating current is produced independently in the wires forming the sides of the prism. The control grid is formed from a number of short wires 6 similarly disposed and carried by axially disposed members 5. The anode is a cylinder 2, and, in order to maintain the mutual conductance uniform, the amount of sag between the ends of the wires is so chosen as to compensate for the variation in distance between the grid and the anode. Specification 476,757 is referred to.

Title: Improvements in or relating to electric plug and socket connectors
IPC: H01R13/703
Filed: 1958-06-16
Abstract: 834,754. Lamp-holders. KRUMM, J. L. June 16, 1958 [June 17, 1957], No. 19264/58. Class 38 (1). The plug-pin 8 of, e.g. a cold cathode discharge tube for use in an explosive atmosphere makes contact with head 5 on metal element 2 slightly before abutment 9 of the plug element engages the end of socket member 6, further movement of pin 8 then moving members 1 and 4 inwards together against springs 10 and 13 until member 2 meets current carrying member 14. Members 1 and 4 cannot be moved independently owing to the jamming of spherical members 17 in such circumstances between waisted surface 19 of member 4 and inner surface 12 of housing 7. Instead of spherical members 17, locking may be effected by making axial incisions in the inner end of member 1 so that radially movable sections are obtained and forming member 4 with a thickened portion so that if one member is moved axially while the other is held in place by a spring, the sections are urged radially outwards and jammed between member 4 and the inner surface of housing 7.

Title: Improvements in machines for trimming and channelling boot and shoe soles
IPC: A43D43/02
Filed: 1951-08-17
Abstract: 760,911. Rough-rounding and channelling machines. SVIT, NARODNI PODNIK. Aug. 17, 1951 [Aug. 31, 1950], No. 19418/51. Class 17 (1). The upper and lower feed shafts and a shaft by means of which the tools are given axial and rocking movements are mounted with their axes substantially in a vertical plane running lengthwise of the machine. The upper shaft 7 receives its rocking movement from a forked lever 24 and cam 6 on cam-shaft 2 and its axial movement from cam disc 9, roller 33 (not shown), and lever 28. The lower shaft 11 derives its rocking movement from cam-shaft 2 through cam 10 and forked lever 75, and its axial movement by operation of a treadle 70 through levers 67,68 and forked lever 65 which operates on collar 49 on shaft 11 against spring 36. A rod 15 which carries a long trimming knife 16 is reciprocated axially by an inclined swash plate having inner and outer members 13, 14 the latter of which is universally jointed to the forked end of rod 15, while a pin 18 or member 14 is constrained to move in a longitudinal guide 17 carried by the inside of the machine casing. Shaft 7 carries a feed check 35, and shaft 11, rear end of which is pressed forwards by a spring 36, carries a shoe support 42. A channelling knife 41 is adjustably mounted in a guide in a holder 40. Depression of a treadle lever 70 moves lever 65 against collar 49 to move the shaft 11 rearwardly against spring 36 to permit introduction of shoe into the machine. Knife 16 trims sole edge and knife 41 forms a channel in sole edge. When the sole is completed, treadle 70 is again depressed and shoe removed. At each operation of the treadle 70, an arm 50 on the shaft 11 actuates a spring-pressed plunger 52 in a cylinder 54 of an oil pump to open a port and drive oil to oil distributing points. The arrangement of shaft permits enclosure of the driving mechanism for the tools in an oil-tight casing of small internal volume, and also the use of a long trimming knife.

Title: Improvements in or relating to strip feeding apparatus
IPC: B26D5/26
Filed: 1965-05-10
Abstract: 1,072,301. Feeding webs. ARENCO AKTIEBOLAG. May 10, 1965 [May 14, 19641, No. 19577/65. Heading B6B. A photo-electric cell senses registration marks on a web 2 being advanced by a pair of feed rollers to a rotary transverse cutter 6. The feed rollers are driven by the output of a differential (19, Fig. 2), one input of which is geared directly to the drive of the cutter 6, the other input of which is geared to the drive of the cutter via gears 20, 21, 23, a variator 24, an electromagnetic coupling and brake 37, 38 and a worm screw and gear 40, 41. The variator 24 comprises a steplessly controllable transmission having friction surfaces connected to each one of the input and output shafts and adjustable movement transmission members for setting to an arbitrary ratio the input r.p.m. and the output r.p.m., and is used to control the amount of overspeed (or underfeed) of the web. A correction is made for miss-register by energizing the brake 38 to stop the worm screw 40. This occurs when a signal from the photo-electric cell detecting a web registration mark coincides with the closing of a switch 60 by a cam 61 on the drive-shaft of the cutter 6. This results in the firing of a thyratron amplifier 62 which allows the coil 58 of a relay 54 to energize, which via a relay 50, results in the de-energization of the electromagnetic coupling 37 and the energization of the electromagnetic brake 38. When correction is not required, relay 50 is held energized by coil 51 via contacts 53 and 55, having been initially energized by coil 52 via cam-operated switch 56. The coupling 37 will remain energized via contact 47, until miss-registration of the web is detected. When a correction is made, a positive voltage is applied via line 76 to the initial stage of a visual stepping register, Fig. 4 (not shown). For each revolution of the cutter 6, the indicator (an energized electric light bulb) is stepped to the next position in the register. Thus the number of revolutions of the cutter per correction is indicated.

Title: Improved method and apparatus for the continuous vacuum distillation of metals
Inventor: DAVEY THOMAS RONALD ALBERT
IPC: C22B19/04
Filed: 1953-07-16
Abstract: 766,877. Refining metals by distillation. BROKEN HILL ASSOCIATED SMELTERS PROPRIETARY, Ltd. July 15, 1954 [July 16, 1953], No. 19783/53. Class 82(1) A metal containing a volatile constituent is refined by passing the molten metal in an attenuated condition (exposed surface is large relative to its volume) into and through an evaporating zone within an evacuated space whereby the volatile constituent is evaporated, passing a second molten metal at a lower temperature into and through the evacuated space, condensing the evaporated constituent and dissolving the condensate in the second molten metal. Preferably the path of the second metal is substantially parallel to the evaporating zone. In the form shown in Fig. 1 for separating zinc from de-silverized lead bullion, the latter is supplied to a vacuum chamber 10 at a temperature of 600-700‹C. by a pipe 14 into a relatively deep annular well 13 and passes up smalldiameter feed pipes 17 into an annular trough 16 from which it overflows on to the inner surface of a convergent spreading tube 12 provided with a flexible joint 12<SP>1</SP>. It then collects in a channel 19 from which it is discharged at a temperature of about 600‹C. by a pipe 20 maintained with a barometric leg. The evaporated zinc condenses in the solid condition on an open-ended tube 22 which is kept at a temperature of 420‹C. by an encircling cooling coil 25 until the deposit 26 is close to the tube 12 when the zinc condenses in the liquid condition, as described in Specification 711,954. Alternatively, the deposit 26 could be pre-formed. Liquid zinc falls into a pool 27 of softened lead bullion at a. temperature above 415‹C. and supplied through a passage 33 surrounding a vacuum pipe 30 which is surmounted by a water-cooled cover 31, the bullion overflowing a lip 35 to form a curtain 36. The pool 27 overflows into a channel 29 from which it is discharged by a pipe 37 also maintained with a barometric leg. In the form shown in Fig. 4, softened bullion is supplied to a vacuum chamber 40 by pipes 43, 42 leading to a well 45 which overflows into a pool 46 which overflows into a basin 49 having a discharge pipe 50 with a barometric leg, the wall 44 of the well 45 being of such height as to leave a free space in the pipe 42 for the removal of gases by a vacuum take-off pipe 47. De-silverized lead bullion is supplied by a pipe 57 and passes over a lip 59 into a recess 58 in a downwardly-concave disc 53 which is rotated by a spindle 51. The bullion then drops on to a ledge 53<SP>1</SP> and is projected outwardly over the lower surface of the disc 53 into a channel 54 full of re-zinced bullion. The channel 54 discharges into a pipe 55 connected to a pipe 56 with a barometric leg. The evaporated zinc condenses on the surface of the pool 46. According to the Provisional Specification a conical tube below the disc 53 projects into the pool 46, and the invention is not limited in its application to the refining of metals.

IPC: B41J19/40
Filed: 1968-04-26
Abstract: 1,199,832. Typewriters &c. OLYMPIA WERKE A.G. 26 April, 1968 [26 May, 1967], No. 19866/68. Heading B6F. A typewriter rack escapement mechanism is provided with a half-letter-spacing mechanism for an error correction space key, the half-letterspacing mechanism including a slidably and pivotally mounted pawl 7, the tooth 6 of which is in engagement with the teeth 24 of a spring biased paper carriage rack 23 and a release lever 19 pivotally mounted in a recess 17 of a spacer 3 and articulated by a link 20 to the space bar (not shown) forming the correction key in its depression position, in which a lug 21 on the release lever 19 abuts a lug 10 on the pawl 7, whereby the distance between lugs 10 and 21, when in their inoperative position, corresponds to half a letter space. When the space bar is released the carriage is enabled to move through a further half-letter space for completion of the letter-spacing escapement movement. To effect an error correction, e.g. by typing an additional letter between two consecutive letters in a word, the space bar is depressed and held in its depressed condition, thereby the lug 21 on the release lever 19 pivots the pawl 7 out of engagement with the rack 23 and a spring 9 causes the pawl 7 to be drawn to the right and into engagement with the following rack tooth. Meanwhile an inclined surface 22 on the lug 21 slides off a complementary surface 11 on the lug 10 to dispose the lug 21 in the path of the lug 10, which is displaced towards the lug 21 by the letter-spacing movement of the paper carriage which is thus arrested in the half-letter-spacing position. On release of the space bar the release pawl 19 is restored to its original position and the carriage thereafter moves a further half a letter space until the lug 12 on the pawl 7 abuts a stop surface 13 on the spacer 3 fast with the typewriter frame. Multiple-action keys.-The space-bar (not shown) is depressed (and held down for error correction) to effect half a letter spacing and then released to complete the full letter spacing.
